Tulipa sogdiana Bunge

Tulipa sogdiana Bunge, Beitr. Fl. Russl. 338 (1852). Fig. 38 Type. Uzbekistan • Inter Bukhara et Kermine, A. Lehmann s. n. (holotype LE; isotypes K 000844627, P 00730919, P 00730920). General distribution. Kazakhstan, Tajikistan, Turkmenistan, and Uzbekistan (Tojibaev et al. 2022). Distribution in Kazakhstan and habitat. Kyzylkum, Southern Ustyrt, Northern Ustyrt, and Mangyshlak. This species grows in deserts on sandy and clay soils. Conservation status. The IUCN conservation status of this species requires assessment. Phenology. Flowering in March – April; fruiting in May – June. Notes. Tulipa sogdiana was first described in 1854 by A. A. Bunge from a desert region between Bukhara and Kermin (Uzbekistan). In “ Flora of Kazakhstan ” (Polyakov 1958), this species was listed in Kyzylkum. Although we did not identify herbarium materials in this area, we believe that it is in Kzyzlkum, as there are numerous confirmed localities of this species in the Uzbekistan part of Kyzylkum (Tojibaev et al. 2022). Tulipa sogdiana differs from similar species of the subgenus Eriostemones by its glabrous filaments of stamens (Everett et al. 2013; Ivashchenko and Belyalov 2019; Tojibaev et al. 2022). Christenhusz et al. (2013) and Everett et al. (2013) placed T. sogdiana in synonymy of T. biflora s. l. However, some authors consider it an independent taxon (Abdulina 1999; Zonneveld 2009; Tojibaev et al. 2022). Wilson (2023) believed that T. sogdiana can be recognized if its uniqueness is proven. Additional studies of this species under natural growing conditions are required to establish its taxonomic position.
